Yoichi Nagumo wasn’t the type to linger.

He was a man of motion—of sudden arrivals and vanishing acts, of jobs that began and ended with clean efficiency and no emotional residue. He had learned long ago that attachments slowed you down, and in his line of work, hesitation meant death.

So why was he here, sitting in your apartment like he belonged, watching you move around the room as though nothing about this situation was strange?

You looked so innocent—folding laundry, humming softly under your breath, strands of hair falling into your face as the evening light caught against your skin. To anyone else, you were harmless, almost forgettable. But the JAA knew better. They had marked you for death because you weren’t harmless at all.

You were the Takeda family’s secret—the adopted daughter taken in after your parents were killed on one of their blood-soaked missions. You had grown up inside the shadows of the JAA’s empire, privy to its whispers and truths. Your innocent façade made you more dangerous than any blade, because you had the potential to destabilize everything.

Nagumo knew that. He’d been sent here for a reason. Yet the knife hidden in his jacket lining had grown heavier every time he thought about drawing it.

“Y’know,” his voice finally cut through the silence, casual and bright, “you really put too much effort into those shirts. One spin in a suitcase and they’re back to looking like a crime scene.”

You glanced up, unimpressed, but there was the faintest twitch at the corner of your lips. Nagumo caught it, tucked it away like treasure.

He shouldn’t be here this long. He shouldn’t enjoy the banter. He shouldn’t notice the way your hands moved with such care, as though even the smallest task deserved precision. But he did.

When the Order first briefed him, the mission was clear: get close, get information, and end it quietly. Yet here he was, dragging his feet, smiling too wide, cracking jokes that gave you glimpses of something beneath his mask. Somewhere along the way, the job stopped feeling like a job.

And maybe that was why, when the knock came at your door and the wood splintered under the force of intruders, Nagumo didn’t hesitate.

You froze, eyes darting to him, instinct tugging at your survival. But Nagumo was already moving.

The grin never left his face, but his entire posture shifted—shoulders loose, steps fluid, every line of his body singing with deadly intent. A man charged at you first, blade raised. Before you could even register the danger, Nagumo’s hand shot out. Steel flashed. The intruder collapsed at your feet, his weapon clattering uselessly.

Two more came in, guns drawn. Nagumo weaved between the muzzle flashes with infuriating ease, like he’d been born to dance through gunfire. One blade flicked from his sleeve, embedding in the first man’s throat. The second he disarmed with a twist of his wrist, sending him crumpling with a smile so quick it looked rehearsed.

You stood there, breath caught in your chest, as silence settled again. Three bodies on the floor. Nagumo straightened, brushing imaginary dust off his jacket, as if he hadn’t just killed like it was second nature.

Then his gaze slid back to you. And for a moment—just a moment—you saw past the playfulness to the sharpness underneath. The truth of who he was: not just the Order’s jester, but one of its most dangerous blades.

The mask snapped back into place with a grin. He leaned lazily against the wall, tilting his head at you. “Guess I should’ve mentioned I’m handy around the house,” he said, tone light, almost teasing. Then his eyes narrowed ever so slightly, voice dipping into something lower. “You really shouldn’t keep doors unlocked, sweetheart. Makes me very emotionally unstable when people try to hurt you.”
